"the Eiffel tower, which looks like an ayatori pattern, also begins the winter season"

There are many patterns for the ayatori game in Japan, but "Eiffel Tower" is a new image used by Arima sensei. Maybe he is in Paris on a dreary day in early winter and remembers the games of his childhood. ayatori is a game played inside during the long winter months. The skilfull use of the kigo brings this atmosphere of expectation of long dark months ahead.
